    摘要： A Raman amplifier applicable to a wavelength division multiplexing optical transmission system is proposed. The Raman amplifier, which can make good use of a wavelength range, comprises an optical fiber for Raman amplification and a pump light introducing means. The zero-dispersion wavelength of the optical fiber and the wavelength of the pump light are nearly equal. The wavelength of pump light is preferably in the range where the absolute magnitude of the chromatic dispersion of the optical fiber is less than 0.3 ps.nm−1.km−1. A range near a zero-dispersion wavelength cannot be utilized as a signal range because waveform deterioration of signal light occurs due to four wave mixing. This range can be utilized effectively as a wavelength range of exciting light for Raman amplification.

    摘要： The present invention relates to a light source apparatus that has a base structure capable of generating SC light and further having a structure that enables the shaping of the spectral waveform of the SC light, power adjustment of the SC light, or adjustment of the frequency of repetition of the pulse train that contains the SC light. For example, a light source apparatus that enables shaping of spectral waveforms comprises a seed light source that emits seed light which is a pulse train or continuous light; an optical fiber that generates SC light from the seed light, and spectrum shaping means for completely or partially changing the spectral waveform of the SC light. The shaping of the spectral waveform changes the maximum power of the seed light by changing the optical coupling efficiency of the seed light source and optical fiber, for example, thereby suitably deforms the spectrum of the SC light.
